PP, PE perforated seepage bellows device: can PP, PE perforated seepage bellows device can continuously produce double-wall corrugated pipe, corrugated perforated bottom of the wave, with high water permeability, acid corrosion, easy to bend, Transportation easy installation and so on. To prevent clogging of sediment, the production line is configured with a nonwoven fabric cover means, set perforated, cover fabric in a production line. Application: Permeable Bellows main application and return to land reclamation, urban areas such as sludge pumping, after the perforated spiral bellows pumping, greatly reducing the mud and sludge dewatering time. Can also be used for landscaping and other fields, the market prospects. The production line after the replacement of the module can produce single-wall corrugated pipe and prestressed bellows, truly a multi-purpose machine.
